  • 28a821c30   Staging: speakup: Update __speakup_paste_selection() tty (ab)usage to match vt ... Browse Code »

    This function is largely a duplicate of paste_selection() in
    drivers/tty/vt/selection.c, but with its own selection state. The
    speakup selection mechanism should really be merged with vt.

    For now, apply the changes from 'TTY: vt, fix paste_selection ldisc
    handling', 'tty: Make ldisc input flow control concurrency-friendly',
    and 'tty: Fix unsafe vt paste_selection()'.

  • d75001358   Staging: speakup: Move pasting into a work item ... Browse Code »

    Input is handled in softirq context, but when pasting we may
    need to sleep. speakup_paste_selection() currently tries to
    bodge this by busy-waiting if in_atomic(), but that doesn't
    help because the ldisc may also sleep.

    For bonus breakage, speakup_paste_selection() changes the
    state of current, even though it's not running in process
    context.

    Move it into a work item and make sure to cancel it on exit.

  • 593fb1ae4   pps: Move timestamp read into PPS code proper ... Browse Code »

    The PPS (Pulse-Per-Second) line discipline has developed a number of
    unhealthy attachments to core tty data and functions, ultimately leading
    to its breakage.

    The previous patches fixed the crashing. This one reduces coupling further
    by eliminating the timestamp parameter from the dcd_change ldisc method.
    This reduces header file linkage and makes the extension more generic,
    and the timestamp read is delayed only slightly, from just before the
    ldisc->ops->dcd_change method call to just after.

  • 78110bb8d   staging: Remove unnecessary OOM messages ... Browse Code »

    alloc failures already get standardized OOM
    messages and a dump_stack.

    For the affected mallocs around these OOM messages:

    Converted kzallocs with multiplies to kcalloc.
    Converted kmallocs with multiplies to kmalloc_array.
    Converted a kmalloc/strlen/strncpy to kstrdup.
    Moved a spin_lock below a removed OOM message and
    removed a now unnecessary spin_unlock.
    Neatened alignment and whitespace.
